Specification of Letters Patent.

Patented July 31, 1906.

Application filed January 28, 1905. SerialNo. 243,166-

artificial silk.

As the fiber of artificial silk is not very hygrosco ic, (accordin toDr. Bro'nnert artificial sil inunwashe condition absorbs from two tofour per cent. of water,) a candle-wick of unwashed artificial silkpossesses .the ca pacity to take up the melted stearin or other candlematerial more easily than a cotton or I linen wick, so that whenrelighting the extinguished candle its flame reaches the normal sizesooner than with candles hitherto in use. Besides the wick of artificialsilk produces or leaves no carbon or charcoal in its combustion, even ifit has not been previously impregnated, and therefore it does not breakoff when the candle is extinguished so easily as on the usual candleswith unimpregnated Wick. and the accidental burning which is sometimescaused bythe broken-0E part whichhas fallen into the melted material isprevented with the new wick. Finally, it should be noted that owingtothe few applications which wastes of artificial silk are used for upto the present candle-wicks made of this material are much cheaper thancotton or linen wicks.

The term artificial silk as herein used refers'to fibers made from asolution of cellu-' lose in a solvent, such as cupro-ammoniacal liquor,(liquor of Schweitzer,) which is a solution of hydrated oxid of copperin ammonia.

Analogous advantages are obtained by using for lamps wicks of artificialsilk, as this material leaves no carbon in its combustion and possessesthe capacity to suck up the "oil more easily than cotton or linen.

What I claim is.

As an improved article of manufacture, a wick, of low hygroscopiccharacter for the purposes set forth, made from the substance known asartificial silk, as herein set forth.

In witness whereof I have hereunto signed my name, this 6th day ofJanuary, 1905, in the presence of two subscribing witnesses.
